Exquisitely recorded on-site at an installation in the Matthauskirche, Berlin that used a set of bells found at the disused St. Inglebert mine and using as structuring material the signal codes that informed miners about the status of the mineshaft elevators. Structured bell tones and silences. At one point the church bells sound faintly outside at the same time. Strangely compelling. Complex tones. Nicely documented with colour photographs.
